Hi all, I'd like to translate the website into French. I've already read at https://www.cinelerra-gg.org/translate-website/ . Thanks for giving me further instructions/credential.

Re: [Cin] Cinelerra & GPU

I think vdpau seems to be the right setting. I also have an Intel processor and an Nvidia graphics card. With vdpau I get the best results. The CPU is hardly used, but the FPS is almost always at maximum. Especially when I switch to X11-OpenGL, I only have 12% CPU load left. Subjectively I have the impression it plays a bit more smoothly. I notice the clearest difference at the fan of the computer. It is hardly noticeable with the hardware acceleration. Without hardware acceleration I get earache because the CPU fan gets extremely loud. Thanks to Andrea for the tip with libva-vdpau post-installation, that's how I got it to work. Here are my tests: X11 CIN_HW_DEV=off ./cin -> CPU 58% CIN_HW_DEV=vdpau ./cin -> CPU 32% CIN_HW_DEV=vaapi ./cin -> CPU 82% X11-OpenGL CIN_HW_DEV=off ./cin -> CPU 48% CIN_HW_DEV=vdpau ./cin -> CPU 12% :-) CIN_HW_DEV=vaapi ./cin -> CPU 80% Sam --

Build 27 April
by Andrea paz 28 Apr '19

28 Apr '19

About the new build 2019-05-27. - First of all thanks for the Tracer plugin; I have yet to test it, I'll let you know. - I noticed that in Arch's PKGBUILD there is twice the "libva" dependency and "libva-vdpau-driver" is missing (NOTE: there is also "ctags" missing without which the installation fails). - I don't really understand how vdpau/vaapi integration works: don't you have to use the string "CIN_HW_DEV=vdpau/vaapi" anymore when starting from terminal? Or do you still have to put it on if you want to activate the GPU? - For now TOP tells me percentages above 100% and the playback FPS are very low, see video: https://www.dropbox.com/s/z3na1r3vmwcnn6n/test.webm?dl=0

New native Tracer plugin checked into GIT
by Phyllis Smith 26 Apr '19

26 Apr '19

GG has created a new plugin, called Tracer. It creates an outline (i.e. traces) around an object after a few points are designated. You can then "fill" the alpha channel with its mask, like with a gradient or another object on another track. Although it works well for still images or objects that stay in the same place on a video like a logo, you can also add keyframes. There is a quick demo at: https://streamable.com/o8bse In the video, you can not see that instead of using the "New" button in the controls menu, I use the right mouse button.

I tested it the same way, but I get the error message. Decoder h264 does not support device type vaapi. HW device init failed, using SW decode. file:/home/spc/cin-test/aerial-shot-of-las-vegas-sprawl-daytime_w18wevlbr__D.mp4 err: Success Under OpenSuse I installed the following package. zypper install libva-devel-2.4.0-lp150.114.1.x86_64.rpm In the Cin settings I have set it to X11. However, I have installed the proprietary drivers, do I need to change this? Thanks again for this implementation. Sam

User Folders/Bins and Delete key
by Igor BEGHETTO 22 Apr '19

22 Apr '19

User Folders/Bins is very useful/powerful but sometimes I delete a thumbnail/item from my userBin (not with "Modify folder" window) and so it is also removed from the Media and from the project. I know that there is the undo function and in CinelerraGG_manual.pdf it is described very well how to delete a file by User Folder in the "Modify folder" window. I think it would be useful, if possible, to be able to remove the media in UserFolder directly in the right side of the Resources window, but without removing it from the Media and from the project (and of course updating the "Modify target" list of the media in "Modify folder"). It would be more natural from a user's point of view. Same thing for the UserClips. I added a screencast at https://streamable.com/iqyhp Thanks. IgorBeg

Using GPU in Cinelerra-GG
by preobraz＠gmail.com 20 Apr '19

20 Apr '19

I apologize that my question with a new topic fell into the answers to another topic - I do not know how it happened. I will try to duplicate it in the new branch, so as not to be confused. I wrote: I did not find anything in the descriptions of the program about using the GPU. Is there such a possibility? Where can I read about it? Ugin.

In the new unified manual, in the Setting chapter (Settings --> Preferences), there are missing or unclear entries (for me). Does anyone know them and how to use them? PLAYBACK A TAB: - Enable subtitles/captioning - Labels cells - TOC Program No RECORDING TAB: - Realtime TOC - DVB Adapter - Follow audio config APPEARANCE TAB: - ffmpeg probe warns rebuild indexes

Insert a video without audio between two edits
by Igor BEGHETTO 18 Apr '19

18 Apr '19

When I have to insert a video without audio, between two edits in Timeline, the audio on the right side does not shift to the right even if the audio track is Armed. I think it would be useful if the audio was moved to the right for the length of the inserted video. Of course, if the audio track is DisArmed, it will not occur. Now, I use a little trick to re-align the video with the audio correctly after the new edit is inserted. I added a short screencast: https://streamable.com/6yxwc What do you think, please? IgorBeg (I write here and not in MantisBT-feature for more discussion)

Waveform generation using ffmpeg filters
by preobraz＠gmail.com 16 Apr '19

16 Apr '19

Hello. I'm trying to generate a 440 Hz sound with the help of FFmpeg of ffmpeg -f lavfi -i "sine=frequency=440:duration=5" test.wav type, but the waveform is: https://www.datafilehost.com/d/ea27d7ec Does Cinelerra incorrectly process the generation, or do I need to change something in the settings? Ugin.
